ABSTRACT:
Irrigation systems which use sprinklers can cause local flooding in the event of either a sprinkler head failure or a broken riser. The result is localized crop damage, irrigation water wastage, land erosion, and deprivation of water for the remainder of the circuit. The disclosed invention provides a method of and, a device for, protecting the irrigation land from the above mentioned potential damage. The disclosed invention comprises an automatic flow shut off device situated between the distribution joint and the individual sprinkler head. The flow shut off device detects and responds to the excess flow caused by the damaged sprinkler and subsequently isolates the water flow to the affected sprinkler. In so doing, the device allows the remainder of the irrigation circuit to operate uninterrupted, temporarily without the service of the damaged sprinkler. This invention not only protects the irrigated land from potential flood damage but also serves water and maintenance costs and reduces irrigation down time.
